Chrissy Teigen was perhaps the best-dressed pregnant lady of the evening, wearing not one, but two, head-turning gowns. She kicked off the evening in a custom Marchesa creation that had a nude underlay and gorgeous red, beading in a floral pattern. Later in the evening, she swapped that stunner for a black, sequined gown with long sleeves and a cowl neckline. She pulled her hair back into a tight chignon to complete the look.

Anne Hathaway went the more avant garde look. The Oscar winner showed off her baby belly in a sheer overlay dress. The black, sheer overlay had modern gold beading and she wore a black, sweetheart dress underneath. She pulled her hair back into a braided ponytail for a fun and funky style.

Eddie Redmayne's leading lady kept to one look for the evening, but it's easy to see why since it was so pretty. Bagshawe wore a black goddess-style dress with an embellished, gold halter neckline. The dress draped around her pregnant figure and looked both comfortable and sophisticated. She wore her hair down in loose waves and donned minimal makeup.

It looks like all three ladies had a good time too! Inside the Vanity Fair after-party, the Redmaynes and the Shulman-Hathaways were spotted chit-chatting and posed for several pictures together. What do you bet they were swapping soon-to-be-parenting tips?
